Description
Technical field
The present invention relates to a kind of water pump more particularly to a kind of whirlpool pump configurations.
Background technique
As shown in Figure 1, Figure 2, Figure 3, Figure 4, at present traditional peripheral pump be by a ring-like parallel fluid channels 2 are arranged in the pump housing 1,
The speedup pressurization of liquid is realized by wheel rotor 6 after front cover 4 by the axis 3 of motor 5.The rotation of impeller 6 can generate liquid from
Mental and physical efforts, because impeller 6 is the multiple tooth shape in two sides, two sides respectively has multiple teeth 62, and rotation enables liquid to be continuously improved in runner 2
Flow velocity, while runner inner wall namely Vortex pump runner sagittal plane 12 to the pump housing 1, form very high impact friction.Separately because of vortex
Impeller of pump 6 is that pressure-raising, the tooth 62 on 6 two sides of impeller are separated by impeller interval face 61 section by section by two drive of the faces R 63 liquid, because
This liquid, which can not be reached, efficiently promotes area of passage, while because the vibration that two sides is separated by the not parallel generation to be formed also consumes centainly
Power influences the flow and lift of peripheral pump, makes its inefficiency.
Summary of the invention
The present invention provides a kind of whirlpool pump configuration, the purpose is to solve the disadvantage that the prior art, reduces flow loss, improves
Effective discharge and lift, improve efficiency.
The technical solution adopted by the present invention to solve the technical problems is：
A kind of whirlpool pump configuration, the pump housing including sequential connection, pump front cover, motor, the axis of motor pass through after pump front cover
The fixed impeller in end, impeller are located at the pump housing and pump in the blade wheel chamber between front cover, it is characterised in that：The pump housing has the pump housing of annular
Runner, pump front cover have the pump front cover runner of annular；Blade wheel chamber has blade wheel chamber's water inlet and blade wheel chamber's water outlet；It is set on impeller
There is the flowing hole of a circle circumference uniform distribution, the side wall of each flowing hole is equipped with the overcurrent tooth of protrusion.
Overcurrent tooth is arc overcurrent tooth, and arc overcurrent tooth is arc-shaped on the section parallel with impeller end face, is impeller
In the bending shape that the low centre in both sides is high on the vertical section in end face.
Overcurrent tooth is straight overcurrent tooth, and straight overcurrent tooth is linear on the section parallel with impeller end face, is leaf
Take turns bending shape high in the low centre in both sides on the vertical section in end face.
Blade wheel chamber's water outlet intersects with pump housing runner afterwards along the axially extending of water outlet.
The invention has the beneficial effects that：
Impeller shape of the present invention does not have middle septal surface, and liquid can run through impeller, the arc of newly-designed impeller overcurrent tooth
The shape of triangle or straight type triangle preferably can adequately drive lifting liquid area of passage, be promoted section by section.By pump outlet
Runner be expanded to close to blade wheel chamber's water outlet, make liquid after the speed-raising of pressure-raising section by section directly quickly through until water pump water outlet
Mouthful, it avoids forming runner inner wall high-strength impact friction, be improved efficiency to reduce loss.

Specific embodiment
In order to illustrate more clearly of technical solution of the present invention, attached drawing needed in description will be made below simple
Ground introduction, it should be apparent that, drawings in the following description are only some embodiments of the invention, for ordinary skill
For personnel, without creative efforts, it can also be obtained according to these attached drawings other embodiments.
As shown in Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, Figure 10：
Vortex pump of the invention includes the pump housing 7 being linked in sequence, pump front cover 9, motor 5, and the axis of motor 5 passes through pump front cover 9
Afterwards in the fixed impeller 8 in end, impeller 8 is located at the pump housing 7 and pumps in the blade wheel chamber between front cover 9, and the pump housing 7 has the pump housing stream of annular
Road 73 (namely runner of pump outlet), pump front cover 9 have the pump front cover runner 91 of annular；Blade wheel chamber intakes with blade wheel chamber
Mouth 72 and blade wheel chamber's water outlet 71.
Impeller 8 is equipped with the flowing hole 80 of a circle circumference uniform distribution, and the side wall of each flowing hole 80 is equipped with the overcurrent tooth of protrusion.
Part of the impeller 8 except flowing hole 80 is impeller outer ring 83.
For overcurrent tooth there are two types of form, a kind of overcurrent tooth is arc overcurrent tooth 81, as shown in Figure 11, Figure 12, Figure 13, Figure 14,
Arc overcurrent tooth 81 is arc-shaped such as Figure 14 on the section parallel with 8 end face of impeller, is on the section vertical with 8 end face of impeller
The high bending shape such as Figure 13 in the low centre in both sides.
Another overcurrent tooth be straight overcurrent tooth 82, as shown in Figure 15, Figure 16, Figure 17, Figure 18, straight overcurrent tooth 82 with
Linear such as Figure 18, is on the vertical section in 8 end face of impeller high in the low centre in both sides on the parallel section in 8 end face of impeller
Bending shape such as Figure 17.
The overcurrent tooth position of both shapes preferably can adequately drive and wear in the flowing hole 80 for directly running through impeller 8
The lifting liquid area of passage for crossing flowing hole 80, is promoted section by section.
The present invention by blade wheel chamber's water outlet 71 along water outlet it is axially extending after can intersect with pump housing runner 73 such as Fig. 9,
